In a longitudinal section of a root, starting from the tip and going upwards, the four zones occur in the following order.
A. Root cap, cell division, cell maturation, cell enlargement
B. Cell division, cell enlargement, cell maturation, root cap
C. Cell division, cell maturation, cell enlargement, root cap
D. Root cap, cell division, cell enlargement, cell maturation

Explanation

Solution

The root structure is described to absorb water and minerals. The root is protected by root apical meristem, which is the continuous state of cell division of root cells. To the upper tip of the plant, it transports minerals and water.

Complete answer: The plant's roots are cylindrical, underground and non-green. Generally, it is the descending portion of the axis of the plant. Into the soil, it expands downwards. Nodes, leaves and buds are missing, but endogenous lateral branches are formed. There are several different regions at Source.
a) Root cap: a thimble-like device called the root cap covers the apex of the root. It consists of parenchymatous cells and is multicellular in nature. It protects the root's tender apex as it works its way through the soil.
b) Meristematic activity region: This layer is located a few millimetres above the root cap. These layer cells are thin-walled, slim, with a thick protoplasm. To produce new cells, they divide repeatedly.
c) Elongation region: The cells proximal to the meristematic region are rapidly elongated and expanded, and are responsible for longitudinal root growth.
d) Maturation region: The zone of cell elongation is gradually differentiating and maturing. This zone, proximal to the area of elongation, is therefore called the maturation region. Some epidermal cells develop a very delicate and fine thread-like structure called root hairs from the area of maturation. The surface area for the absorption of water and minerals from the soil is increased by root fur.
So, option C is the correct answer.

Note: Roots travel in the direction of light and in the direction of gravity. The roots are also said to be geotropically positive and phototropically negative. Roots may have several purposes, such as providing the plants with support and even serving as a food storage reserve.
